What is the preferred unit of measure for power?

Explanation:
Power is the rate at which energy is transferred or work is performed. In the SI system, the unit for power is the watt, defined as one joule per second. In electrical terms, power equals voltage times current (P = V × I), so one watt represents one volt at one ampere. For larger amounts of power, we use kilowatts and megawatts. The other units shown measure different electrical quantities: ohm for resistance, volt for electric potential, and ampere for current, not for power.
